A generator system includes an AC generator having one or more phases; a transformer having the same number of phases as the AC generator; for each phase of the AC generator, only a capacitive element receiving the current from a respective output winding of the AC generator for conveying in series to a primary winding of a respective phase of the transformer, each capacitive element having a first terminal electrically connected to the respective output winding and a second terminal electrically connected to the respective primary winding; a prime mover in driving engagement with the AC generator; and a load connected to a secondary winding of the transformer. A method to reduce the mechanical input to an AC generator comprises reducing the counter torque of the AC generator by conveying, in series only, the current from the AC generator to a transformer via, for each phase of the AC generator, a respective series-connected capacitive element having a first terminal electrically connected to an output winding of the AC generator and a second terminal electrically connected to a primary winding of a respective phase of the transformer.
